I have a working site:
The culture site collection has a subsite (icon show it to be a workspace) that still shows up in the Current Navigation, SharePoint Designer and the Sites and Workspaces listing. However the link is very wrong, and I cannot access the site.
It used to be

Which give a 500 INTERNAL SERVER ERROR warning. None of the content listed in the Site Hierachry treeview is accessible. It all throws this same error regardless of the link.

NEW INFO I am now a site collection admin. I enabled the Publishing feature and I cannot access the Manage Content and Structure page. Unknown error.
Still looking for settings to reset on the parent site.
